To all whom it may concern Pie it known that l, Emm GRUExrnLDr, a subject of the Emperor of Germany, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certa n new and useful Improvements in and Relating to Operating Mechanism, of which the following is a specification. I

This invention rel ates tooperatingmechanism for motor vehicles. particularly operating mechanism forthe control member of a motor. This invention is especially adapted for use in connection with an electric controller, the circuit. controlling member of which may be moved in opposite directions to change the direction of rotation of the motor armature shaft.

I have illustrated my invention as applied to the controller for an electric vehicle, which in ordinary use is driven forwardly and rearwardly by an electric motor,

For the purpose of illustration 1 have, in the accompanying drawings, shown and herein described one form of appliance embodying my invention.

Figure 1 is an elevation, partly in section, of a portion of the vehicle frame, the controller and the controller operating" mecha nism embodying'my invention.

Fig. 2 is a sectional view through the controller mechanism on the line 2 -2 of Fig.

Fig. 3 is a view on the line 3-3 ofFi g. 2.

Fig. t is a top planview showin'gthe parts in neutral position and the control lever in position to operate the controller for driving the vehicle forwardly;

Fig. 5 is a top planview showing the position of the control lever when the vehicle is being driven rearwardly.

In the drawings,- 1 indicates a portion of I a vehicle frame. 2 indicates a casing orhousing within which is mounted acontroller for controlling the electric motor (not shown) of the vehicle, having a movablecircuit opening and closing member 2", adapted who moved in one direction from neutral position to close the circuit and cause the armature shaft of the electric motor to rotate in one direction; and when moved in the opposite direction from neutral position to close the circuit and cause the armature shaft of the electric motor to rotate in the reverse direction. The movable member; of the controller is prefer bly mounted on a s raft;whieltextends out i" ie the timings 2.

The movable member 9? is provided with a sprocket 2 to receive a chain 2, by which it is rotated in either direction. The casing 2 may be mounted in a well known manner on the frame 1 by one or more brackets 2 3 indicates'a su 'aporting frame preferably fixed by bolts 3'" to one side of the casing 2. Extending from the frame 3 is a pair-of arms 8", which, at their free ends are provided with collars 3 arranged to support a bearing sleeve 3 The sleeve 35 may be fixed to one of the collars by a bolt3 the inner end of which extends into an opening formed in the'sleeve. f v

I at indicates a sleeve shaft rotatably mounted in thebearing sleeve 3. The sleeve shaft 4: extends upwardly from the supporting frame 3, the latter being preferably arranged so as to support the sleeve shaft A- at one side of the drivefs seat in the vehicle in convenient position for operation as will be sprocket chain 2 extends around the sprocket t? and thus transmits its rotary motion to the sprocket 2 whenever the sleeve shaft 4 is rotated. V v f 5 indicates a tubular end piece arranged at the upper end of and fixed to the sleeve shaft 4 in any desired manner. The tubular end piece 5 is provided at its upper end with a segnient-al flange 5' At 5, 5, the flange 5 is formed with a pair of openings or slots, preferably spaced from each other a distance of approximately 60 on an arc struck from the axis of the sleeve shaft 4. The slotsfifi 5 are preferably elongated and extend inwardly in aradial direction from the outer edge of theflange 5.

6 indicates a'supporting inemberfor the upper end of the sleeve shaft 1-. The member 6' preferably comprises a collar 6, in which the end piece 5 is mounted, and; a pair of arms projecting laterally from the adjacent part of the vehicle frame 1. The member 6 is arranged between the free ends of the arms 7 and rigidlyconnected thereto, as by bolts 71 The piece maybe provided with an annular shoulder 5 which engages the collar- 6? and prevents endwise movement of the tubular piece'5 downwardly.

8 indicates a shaft rotata-loly mounted within-the sleeve shaft A: At; 8 the shaft is 1 iii preferably extending laterally in a direcenlarged to form an annular shoulder which has bearing 1n the rabbeted portion 4 of the 'rsleeve shaft 4. 9 indicates a lever pivoted movement of the shaft 8.

As will be clearly understood from the foregoing description, the shaft 8 andthe plvot connection between it and the lever 9 permits the latter to be freely oscillated toward and from the driver of the vehicle and also to be'raised and lowered in vertical planes. 1 v

10 indicates a look pin fixed to and depending from the lever 9 and adapted to be inserted or projected into either one of the slots 5*, 5", whenever the lever 9 is moved into a position with the lock pin in registrywith one of said slots. When the lock pin 10 is inserted into one of the slots 5, 5 of the flange 5, it serves as a connection between the shaft 41- and lever 9, where- 'by the movement of the latter will rotate the shaft 1 in one direction or the other. The

construction and arrangement of the connec tions between the controller shaft 2? and'the shaft t are preferably such that when the latter is rotated in anti-clockwise direction (as viewed in Fig. 1), the motor armature shaft will drive the vehicle in a forward direction; hence, when the lever 9 is moved into proper position and swung downwardly to insert the lock pin 10in the slot 5 ,and then swung or moved away from the driver about the aXis of the shaft 8, the controller 2 will, be operated so that the motor vehicle will be driven forwardl also, when the lever 9 is moved into a position with the-lock pin. 10 above the slot 5 and swung downwardly to insert the pin 10 therein, and is then moved toward the driver about the axis of the shaft 8, the controller will be operated so that the motor vehicle will be driven rearwardly.

11 indicates as an entirety means. for

guiding and controlling the movement of the lever 9. The means 11 are preferably -inter posed between the lever 9 and the supporting member 6.

' Of the guide and control means 11, 11' indicates an arm fiXed to and depending from the lever 9. 11 indicates a guide pin tion toward the axis of the shaft 8.- This pin 11 may be rigidly connected to the arm 11 in a well known manner. 12 indicates a guide plate in which are formed a pair of ingeither upwardly or downwardly. 12

12" indicate gate-ways or slots formed in the walls of the guide platelQ. The gateways 1%, 12, extend downwardly from the upper edge of the plate 12, and at their lower ends they merge into or communicate with the guides 12 12, respectively. As shown in the drawings, the gate-way 12 is arranged at-and communicates with the rear end of the guide 1%, whereas the gate way 12" is arranged at and communicates with the front end of the guide 12 The gate-ways 12 12" provide a passage way for the guide pin 11 so that when the lever 9 is swung downwardly to insert the lock pin 10 into one of the slots 5 5 the guide pin 11 may enter one of the guides 12, 12", and then move horizontally therein to operate the controller. The opposite end walls of the guides 12, 12 form stops to limit the movement of the guide pin in either direction. I

As shown at 12, the wall of the plate 12 is cut away to form a slide on which the guide pin 11 may ride when being moved toward or from one of the gate-ways 12 12*; also, the opposite end walls of the cut away portion 12 form shoulders or stops 12?, 12, which limit the movement'of the guide pin 11. These stops facilitate the operation of the lever 9, because they readily indicate to the driver when he has moved the lever to that position which will permit him to swing the lever downwardly and connect it with the sleeve shaft a.

The guide plate 12 preferably comprises a section of a spherical shell, the axis of which is the axis on which the lever swings in horizontal and vertical directions. 7 This form of construction provides for the guide pin 11 suitable curvedv guides struck from the axis on which the lever 9swings. The plate 12 is preferably formed integral with the supporting member 6.

As will be understood from the drawings, the gate ways 1%, 12" are arranged. approxin'iately apart about the axis of the shaft 8, and on radial lines cutting the slots 5, 5". From this construction and arrangement it will be apparent that when the lever 9 is moved horizontally to the position which will permit the guide pin 11 to enter either one of the gate ways 12 12", the lock pin 10 will be superposed above the adjacent slot 5 or 5".

13 indicates a hollow casing the walls. m.

13" in the casing 13. Phe innerend of the kee en 13 extends throu h eninws 13,

p #3 p b sired speedaccording 4o 13 13 formed in the shaft 4., end piece 5 and shaft 8, respectively, which openings are arranged to register with each other and with the opening 13" when the shaft 4: is in neutral position and the lever 9 positioned to insert the lock pin '10 in the slot 5*.

1& indicates a spring operated device, such as a ball, mounted in an opening 1490f the member 6 and adapted to engage the walls of the notches 13. formed in the keeper 13 to normally maintain the same in either alocked or unlocked position.

15 indicates an insulated wire forming part of an electric bell circuit. This wire leads through the lever 9, as shownin Fig. 3, to a pair of contacts (not shown) within the handle 9. The contactsa-re operated by a push button 15, mounted in the free end of the handle, to complete the circuit.

In operation, assuming that it is desired to drive the vehicle forwardly, the lever 9 is moved rearwardly or toward the driver until the guide pin 11 engages the stop 12. The driver then moves the lever 9' downwardly, causing; the guide pin 11* to move through the gate. way 12 into the guide 12 and the lock pin 10 to enter the slot 5 The lever 9 is now connected to the sleeve shaft at and may be moved forwardly to connect in the current to drive the vehicle at any deto the distance the lever 9 is operated. In this latter operation, the guide pin 11 slides through. the guide 12 and. the walls thereof prevent the swingingof the lever vertically during such movement. To stop'the vehicle,gthe' lever 9 is returned to neutral position, or at the rear endof the guide 12. 7

If now it is desired to drive the' vehicle rearwardly, the lever is elevated, the guide pin moving upwardly through the gate way 1% to remove the lock: pin 10 with the slot 5 The lever 9 is then moved forwardly until the guide pin engages the stop 12 after which it is swung, downwardly. This latter operationhas the effect of moving the guidepin through the gate way 12" and. the lock pin; 10 into the slot 5. If now the lever. 9' is moved rearwardly the current in the motor will be reversed, causing the vehicle to be driven. rearwardly.

. From the foregoing description it will be seen that I have provided a constructlon m which the. operation of the vehicle both forwardly andrearwardly is controlled by the movement of a lever throughout a relatively shortlarc, so that of'the ear either direction can be accomplished without changing. ones position. I

By my invention, the control lever is guided and controlled in its movements in either direction, so that if for instance the driver desires to go forward and has moved the pin 11 into the gate 1%, he cannot move-the lever 9 in any direction except forwardly through. the guide 12 Again, when the lever 9' is once connected to the shaft 4L and the latter operated, it cannot be disconnected therefrom except by movement back to starting position, where the current is entirely out off. Furthermore, bythe use of my'invention it is impossible, when shutting off the current, to reverse the motor by mistake because it is always necessary, after moving the lever to neutral position, to disconnect it from the shaft d by an upward movement, then move it forward to the position'wherein the pin 10 registers with the slot 5 and finally swing the lever downwardly. 'As the guides 12*, 12*, are not connected together and'each has but one open end, it will he seen that the. pin ll cannot be changed from one guide to the other except by first moving it back to the open end of the guide in which it is at any time located and then by removing it therefro'n'i, as just described.

'From the foregoing description it will also be seen that the lever 9 is movable to operative and non-operative positions; when moved to operative position the vehicle may be operated as desired, but when the lever is moved to the non operati-ve position it' is freely movable about its pivot.

As the pin-11 is fixed to the lever 9', the

latter is guided and controlled in itsmovements to turn on the current to drive the vehicle as desired.
